Edit Background Map dialog

Use this dialog to edit a map from the Background Maps tab of the "Administration: Manage Map Data page." Before editing a background map, add layers using the Layers tab. A background map is a non-interactive map that serves as a base for the map view. It might display a satellite image or a map with roads. (A background map is referred to as a "tile" in MapViewer.)

For more information, see "Administering Maps" in System Administrator's Guide for Oracle Business Intelligence Enterprise Edition.

Components

Name

Use this field to enter the name of the map.

Location

Displays the location of the background map in the data source from MapViewer. Click the Location button to display the "Import Background Maps dialog" for importing a different map. If you select a background map that includes a different number of zoom levels, then the zoom levels are automatically adjusted for the layers that are associated with the map by scaling their ranges.

Description

Use this field to enter a description of the map, which is displayed in the following locations:

On the Background Maps tab of the Administration: Manage Map Data page.

As a tooltip for the map when selecting a map from the list, when editing the map view.

Interactive BI Layers and Feature Layers area

Use this area to specify the available map layers from either an Oracle Database or other non-BI associated content (known as a Feature layer) and their zoom level. The first time that you display this dialog after adding a map, this area lists any appropriate layers that are specified on the Layers tab, with their default zoom level settings.

A Feature layer is used to overlay predefined styles on maps and is indicated by an icon with a small yellow and black diamond.

The layers are listed from bottom to top, in terms of how they are applied to the map. A sample order is Countries, States, Cities. The lower level layers generally have the lower zoom levels. For example, if you have a States layer and a Cities layer, then include lower zoom levels for State than City.

This area contains the following components:

Click the Add Layers button to display a list of the layers that have been imported on the Layers tab, then select the layers to add to the map. When you add a layer that is part of the map definition from MapViewer, the layer displays at its default zoom levels. If the layer is not part of the map definition, then specify the zoom levels yourself.

Click the Sort Layers By Zoom Level button to list the layers in ascending or descending order based on visibility on the map. The sort order that is specified here does not affect the order in which layers are applied on the map. Instead, the sorting order affects the zoom levels. For example, the States layer might have zoom levels 1 through 3 and the Cities layer has zoom levels 4 through 9. The lower layers have the lower zoom level numbers. The zoom levels that you specify correspond to the tick marks on the zoom slider on the map.

You can include both layers that have been associated with a BI column by using the "Edit Layer dialog" and layers that have not been associated. Ensure that BI layers are ordered higher than non-BI layers. If a non-BI layer is ordered higher than any BI layers, then the non-BI layer is displayed on top of the lower BI layers on the map, which prevents the BI layers from being interactive.

Click the Turn On Layer Visibility or Turn Off Layer Visibility button to control the visibility of layers on the map. Use the buttons to indicate whether the layer is visible in the Preview map in this dialog only. The layer is still visible on a map view. You can modify the zoom levels for a layer with a visibility turned off.

Click a cell under a zoom level for a layer to see one of the following:

If you click a blue cell that is between other blue cells, then you see a popup menu with Clear Left and Clear Right buttons, which allow you to change the zoom level in either direction. For example, if you click the cell for zoom level 4 and click the eraser on the right, all cells to the right are cleared for that zoom level.

If you click a blue cell that at the end of a line of blue cells, then the cell turns white to indicate that it is no longer part of that zoom level.

If you click a white cell, then you increase the zoom level on either side of the existing blue cells. For example, suppose cells 4 through 6 are colored blue to reflect the zoom level. If you click in cell 2, then the zoom level becomes 2 through 6.

If you do not set any zoom levels for a layer, then that layer does not display on the map.

Hover over the layer name to display a More menu from which you can make the following selections:

Delete — Deletes the layer from the Interactive BI Layers area. The layer continues to be available on the Layers tab and can be added to this area again.

Move Up or Move Down — Moves the layer up or down so you can specify the order in which layers are applied to the map.

Reset to Default Visibility — Resets the current visibility range for this layer as defined in the underlying map definition. If this layer is not natively associated with the map, then this option is disabled for that layer.

Use the yellow border that surrounds the column of boxes for a zoom level to determine which zoom level is currently displayed in the map area.

Map area

Use this area to specify how the map is displayed to users. Use the panning and zooming controls to affect the display of the map. If you hover over the zoom slider, then you see tooltips that specify the names of the layers that are currently associated with that zoom level.
